General Information

Silicon mortar is adhesive material matched with silica brick. Our silicon mortar has such advantages as high adhesive strength, high refractoriness, excellent refractoriness under load, and good installation performance.

 

Feature

Control the liquid system, Adhesive, Polymer's rheology and thixotropy.
As additive agent used to prevent subside,thickening and prevent sagging.
Reinforce HRC high temperature sulfuration silicon rubber and RTV-2K room temperature sulfuration silicon rubber.
Improve the quality of the powder, and improve the liquidity and anti-blocking characteristic.


Application
paint and coating, Unsaturated polyester resins, laminating resins and gel coat.
HCR high temperature sulfuration silicon rubber and RTV-2K room temperature sulfuration silicon rubber.   Adhesive and fluid sealant, Printing ink, Cable rubber,Plant protection,Food and cosmetics.

Q:Why is the three oxidation of two silicon is very harmful impurities in silica brick
Heating calcination is the best way to extend this sort of impurity removal. Remove impurities
Q:What is the silica refractory products?
High silicon content in high temperature expansion sintering temperature between 1390-1410 in furnace arch
Q:What role does silica play in refractories?
The production of clay brick refractory clay raw material is natural, its main mineral is kaolinite (formula Al2O3 - 2SiO2 - 2H2O), clay brick containing SiO2 in 45% ~ 65%, belongs to the weak acid refractory materials, have a certain ability to resist acid slag, but easy to be alkaline slag erosion.
Q:How to judge the quality of brick, clay brick, high alumina brick furnace from the appearance?
Mainly depends on the color and density of brick. Another black clay brick and brick with iron oxide formation and how much the size of bricks
Q:The hot blast stove when the temperature did not rise against the brick interface decreased
How to keep the brick masonry temperature not lower than 600 DEG C, while the exhaust temperature is not higher than 400 DEG C.
Q:Common bond brick?
When adding ingredients, the amount of lime added shall be converted to CaO, and the amount of addition varies depending on the product, usually fluctuating at 1.5~2.5%. For example, the production of coke oven silica brick, the dosage of CaO is 2.0~3.0%; the production of electric furnace top brick, the dosage of CaO is 1.4~1.75%.
Q:The introduction of silica brick
The silica mineral phase is mainly composed of tridymite and cristobalite, there is a small amount of quartz and glass
Q:Such purpose and scope please give me detailed points thank you
Acid refractory brick is mainly composed of tridymite and cristobalite and quartz and a small amount of residual glass phase.
Q:The introduction of silica brick?
The characteristics of silica brick:Brick belongs to refractory materials, with strong resistance to acid slag or acid solution erosion ability, high load softening temperature are excellent properties of silica brick, usually 1640-1680 C.The use of silica brick:Mainly used for masonry brick oven carbonization chamber, a combustion chamber and a partition wall, glass furnace and kiln roof, pool wall, high temperature hot blast furnace, glass furnace, load-bearing pool wall, hot blast stove, baking furnace of carbon bearing part of high temperature furnaces etc.. Rongsheng with refractory
Q:How to improve the thermal conductivity of the coke silicabrick rate?
To improve the thermal conductivity of silica brick for coke oven rate method:Manufacture of high density and high thermal conductivity of silica brick, adding additives such as CuO, Cu2O, TiO2, Fe2O3, (FeO), can improve the thermal conductivity of silica brick.
